Study of Effect of Waterlogging on Root Anatomy of Ragi and Rice

S.S. Kulkarn and P.D. Chavan

In present study, effect of waterlogging (4, 8 and 12 days) on root anatomy of ragi and rice was studied. It was noticed that the formation of aerenchyma tissue in the ragi roots was induced due to increasing waterlogging treatment. On the other hand, rice roots grown under normal conditions had well developed aerenchyma tissue and treatment of waterlogging did not cause any noticeable change in root anatomy. Thus development of aerenchyma in response to waterlogging in ragi roots would certainly help to supply O2 to the root metabolism. Activity of acid phosphatase was declined in both the species during waterlogging, indicating that its involvement in aerenchyma formation was no any significance. There was decline in calcium content in ragi roots due to waterlogging whereas in rice root an increase was noticeable. Thus a decreased calcium level in ragi roots may limit the availability of calcium for the formation of new cell wall material.
